Limit queue size with TTL or max-length Another recommendation for applications that often get hit by spikes of messages, and where throughput is more important than anything else, is to set a max-length on the queue. This keeps the queue short by discarding messages from the head of the ...
You can use this feature to forward messages from a queue to another queue or an exchange. The message source and message destination can belong to different instances or vhosts in the same region or different regions. Usage notes Extra fees are incurred. The total fees that you are charged...
